Transient transgenesis strategy for rapid evaluation of enhancer activity upon PhiC31-mediated targeting. (A) Schematic of PhiC31-targeted integration system, designed for cis-regulatory element analyses in transient transgenic embryos. ?-2.4 shh?, 2.4 kb upstream region of shh gene; ?shhABC?, shh complete introns 1 and 2, with ar-A, ar-B, ar-C enhancers (M�ller et al., 1999; Ertzer et al., 2007). (B) Detection of reporter activity in embryos injected with construct containing the shh cis-regulatory elements by in situ hybridisation (B) and fluorescence microscopy (C). Arrows indicate activity in shh expression domains, resulting from successful integration of the shh cis-regulatory cassette in to the attP site of uobL12, whereas arrowheads indicate the activity of the crygc promoter in uobL12 recipient line. Scale bars: 150 μm.
